Widget Interaction Component in Multiplayer

How do I set up Widget Interaction Components and Widget Components properly for Multiplayer?

I implemented the Interaction Component in my Player Character, and the Widget Component in an Actor with a screen, that has a few selection buttons and an image that shows the current selection. It works in Singleplayer or when alone in a session, but as soon as a second player joins the game, not even the Server sets the butten in it’s hovered state, when anyone hoveres over it.

I read that click events don’t work, so I used pressed events. These seem to work, but not for the clients, I already tried RPCs, doesn’t change anything, wich is confusing since they seem to register the press, since they get set to the pressed state for the client.

My problem in short:

  1. The hovered state doesn’t get set properly for anyone.
  2. The button presses don’t get sent to the server properly for the clients.

Does anyone know what I could do, to resolve these two issues?
